Abstract

Global warming is an increase in the average temperature of the earth's surface due to the effects of greenhouse gases, such as carbon dioxide. Global warming can be prevented by maintaining forest structure and increasing tree density in the forest, one of which is in the mangrove forest ecosystem through rehabilitation using bund techniques. This research aims to analyze the type composition and structure of mangrove stands, estimate carbon storage and carbon dioxide uptake in five-year-old mangrove stands in Jakarta. The research method used is vegetation analysis through simple random sampling. Data analysis was obtained through vegetation analysis, environmental factor analysis, and estimating carbon storage and carbon dioxide uptake in mangrove stands. The research results showed that the species growing at the research location were Rhizophora mucronata and Sonneratia caseolaris. Carbon storage in mangrove stands at the research location is 72.99 tonnes/ha, with a carbon dioxide absorption capacity of 267.63 tonnes/ha. Keywords: carbon stock, carbondioxide absorption, mangrove, guludan technique

Abstract

Mangrove ecosystems are essential for maintaining coastal ecological stability, yet they remain highly vulnerable to degradation due to increasing anthropogenic pressures. Rehabilitation efforts are a strategic step in restoring the ecological functions of these areas. This study was conducted to evaluate mangrove planting through growth parameters and to analyze the effect of planting distance on the growth of 11-month-old Rhizophora apiculata at a rehabilitation site in Purworejo Village, East Lampung. The survival rate at a planting distance of 1×1 m (95%) and 2×2 m (85%) showed good results, while at a planting distance of 1×2 m (68.3%) showed less favorable results. The stem height measurements indicated that the highest average was at a planting distance of 1×1 m (41.9 cm), followed by 2×2 m (36.7 cm), and 1×2 m (27.2 cm). In contrast, the diameter measurements showed that the largest average was at a planting distance of 1×1 m (1.17 cm), 2×2 m (1.10 cm), and 1×2 m (0.84 cm). Analysis of variance shows that the appropriate planting distance arrangement can improve the efficiency of space utilization and nutrient availability, as well as contribute to the structural growth of mangroves in the early phase.
